T1058Integral membrane protein
(X-ray phasing)
Henning TidowUniversity of Hamburg
The model you sent me (from the leading group) worked for MR and we finally solved the structure by MR-SAD. I am still astonished that the human expert model worked, while none of the server models we tried did not (as they were rather similar). Great job!

H1097 [T1092, T1093, T1094, T1095, T1096]AR9 RNA Polymerase
(threading poly-A model into cryo-EM map)
Petr LeimanUniversity of Texas (UTMB)
Both my student (Alec Fraser in CC) and I are shocked… stunned… by the quality of the model… We need to re-evaluate what we do here. Alec remarked that he has just learned cryoEM and it is already an antiquated field. My conclusion - you do not need a $10M microscope to get an accurate model. You need to know people who can model your protein for you. Or you learn how do modeling yourself. Seriously, this is mind boggling. You would not believe how much effort we have put into getting this structure. Years of work… Both, cryoEM and crystallography… I mean, this is really shocking...

T1070 attachment region to the phage tail
(identify registry error)
Osnat HerzbergUniversity of Maryland
Unbelievable. They have predicted residues 16-75 correctly with an RMS of 1.26 A. Also, the prediction includes a different assignment of a cis proline (P236) than my original assignment. It turned out that the predicted version is correct because it enables repositioning of a tyrosine residue (Y247) in the right place. The change, together with another adjustment ultimately results in a 2-residue shift of 20 residues (237-256).

T1100Transmembrane receptor
(NMR model could not help to solve the same protein)
Andrei Lupas, Max Planck Institute, Tübingen
I cannot overstate my excitement at the fact that Marcus solved the structure of Af1503 by molecular replacement with the models of group g427 and sent around the coordinates today. I will let him gloat over his success and share the structure when he is ready.
